This chapter examines factors that affect the total money bet on races in Hong Kong and also how that money is distributed between different pools. The conclusion is that quite different processes are at work, but good predictive models are feasible, enabling the detection of the impact of relatively small changes in the betting tax, particularly on how the money is distributed across pools and also enabling us to detect what attracts gamblers to bet more or shift money across pools.
